Formula
ΔS_t = S_t − S_(t−1)Apply the source-defined TNFD Recommendations method only within the disclosed location, ecosystem and value-chain boundary. TNFD Annex 1 metric A15.0 explicitly calls for annual changes in ESG rating scores over the past three years. It is a reportable outcome series, but score-provider, scale and methodology context must be retained because no universal score unit or rating method is specified.
Variables
| Symbol | Variable | Definition | Unit |
|---|---|---|---|
ΔS_t | Year-on-year ESG rating score change | Change in the organization’s ESG rating score between the reporting year and the preceding year. | Dimensionless |
S_t | Current-year ESG rating score | ESG rating score for the reporting year from the identified provider or source. | Dimensionless |
S_(t−1) | Prior-year ESG rating score | ESG rating score for the preceding reporting year from the same identified provider or source. | Dimensionless |

Evidence and status sources
Sustopedia checked each record-specific claim directly against primary publisher material. Labels distinguish current measurement authority from future compatibility and corroborative, legal, edition, or method status context. Corroborative evidence can support a stated limitation but cannot establish the core measurement by itself.

Source-edition basis: Recommendations of the Taskforce on Nature-related Financial Disclosures, September 2023.
- Identify the ESG rating provider or source for each reported score.
- Disclose the rating scale, score direction and any provider methodology or scale changes affecting comparability.
- State whether a score was restated and explain material changes in score coverage, methodology or underlying data.
- Report the annual scores and the corresponding year-on-year changes for each of the previous three years.
Record-specific limitations
- ESG rating scores and score scales are provider-specific and may not be comparable across providers.
- Changes may reflect changes in a rating provider’s methodology, coverage, data inputs or scoring scale rather than changes in the organization’s performance.
- The source does not specify a universal rating provider, score scale, unit or normalization method.
Interpret this metric with the stated reporting boundary, period convention, value shape, and unit. Results prepared with different boundaries or conventions may not be directly comparable.
Measurement evidence supports the core record-specific claims described above. Corroborative evidence can support limitations, while compatibility and status sources provide their separately labelled context. None of these cards by itself determines an organisation's legal applicability, filing readiness, assurance status, or compliance conclusion.
